(GRANTED 'UNDER ATHE PRovIsIoNs or THE ACT or MARCH 3, 1921, 41 STAT. L., 1313.)

To all whom t may concern:

Be it known that I, EDWIN .Teams GAR- FIELD MACINTYRE, a subject of the King of Great Britain, and resident of Clarence, in

rovince of Ontario, `Dominion of Canada, yhave invented certain new and useful Improvements in Oil Burners, and do hereby declare that the following is a full, clear, and eXact description'of the invention. such as will enable those skilled in the art to which itappertains to make and use the same.

Thisfinvention relates toimprovements in oil burners adapted for use with crude oil and other heavy hydrocarbons and the objects ofjthe invention are to facilitate atomizing the oil and mixing the same with the requisite proportion of steam to form a combustible mixture, to increase the efficiency of the burner and permit of the several parts being readily assembled and disassembled, to so control the flow of the oiland steam that the size of the flame may be adjusted to -suit the conditions under which the burner is working and generally to adapt the'severalparts'to better perform the functions required of them.

With the above and other objects in view the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings;

Figure 1 is a sectional elevation of a boiler setting embodying the present invention.

Figure 2 is a longitudinal section of the improved burner,

Figure 3 is an enlarged longitudinal section of the ejector.

Figure 1 is a transverse section on the line 2-2 of Figure 2.

Like characters of reference refer to like parts in the several gures.

Referring to the drawings, oiler of any the lire box doorway 11 A represents a usual construction below which 10 is located, provided with a having an orice therethrough through which the improved oil burner BV extends.

This oil burner B consists of an inner tube 12 having a plurality of curvilinear slots 13 therein staggered relatively to each other and this tube is provided at one end with a cap 9 forming a dead end while the other en d of the tube is threaded as shown at 14.

A reducing union 15 makes threaded engagement with the end 11 and is also connected to one end of the outer pipe 16 the other end of which is threaded to a cap or cover 17 having a plurality of curvilinear slots 1 8 therethrough.

The outer pipe 16 is spaced from the inner tube 12 forming` an annular passageway or chamber 19 to which superheated steam is delivered from the pipe 2O passing through the union 15.

The tube 12 is connected to the conduit or pipe 21 which in turn is connected through the union 22 with an ejector C by means of which a stream of oil is induced and delivered to the inner tube 12 in a manner to be made clear hereafter.

The ejector C is provided with a conduit 23 the bore of which tapers from intermediate of its length outwardly towards both ends and in the shorter tapered end a steam nozzle 24 is located.

This steam nozzle is positioned by a coupling 25 and is adapted to be connected'by the pipe 26 to the pipe 27 which is attached through a pipeline to the dome 28 of the boiler so that dry steam will flow through the pipe 27 into the conduit 26 and thence through the nozzle 21 and conduit 23 and be delivered into the inner tube 12.

This flow of steam can be regulated by the manually operated valve 29 to suit the requirements and the well-working of the device. The ejector C is provided intermediate of its length with an inlet opening 30 which is connected to the pipe 31 communicating with the oil reservoir 32 and the pipe 31 is provided with a valve 33 by means of which the flow of oil delivered to the ejector C may be manually controlled.

In the embodiment illustrated the pipe 2O is shown connected to the pipe 27 by means of a T-piece but it will be understood that super-heated steam from any source might be delivered through the pipe 2O to the chamber 19 and the object in showing the connection illustrated in Figure 1 was for simplicity of connection and to dispense with a plurality of steam pipes.

When a boiler is fitted with a burner of this description, and after steam has been v19 and lthere meeting with initially raised, the valve 29 is regulated allowing steam to flow from the dome 28 through the pipe 27 tothe nozzle 24 and the valve 33 is then opened to allor oil to flow from the reservoir 32 into the pipe 31 and be thus delivered to the ejector.

As the steam passes from the nozzle 24: through the conduit 23 an entraining action takes place and a film of oil passes into the conduit 23 Where intermixing with the steam it is partially vaporized and passing through the pipe 21 into the tube 12 is discharged through the slots 13' in thin lms.

Superheated or dry steam simultaneously the chamber the partially atomized oil and steam completes the atomization and the combustible mixture is discharged from the curvilinear slots 18 in the cap 17 where it is lighted.

`When thelooiler is in full Working order the valves 29 and 33 may be adjusted to give the desired amount of combustion to maintain the steam in the boiler A at the desired predetermined pressure.

It will thus be seen that the operation of the burner is manually controlled to give the best possible efficiency While the arrangement of the several parts is such that they may be readily inspected at all times.

It should also be carefully borne in mind that there are no moving parts in the passes from the pipe 2O into 5 burner and this consequently reduces the liaused in low pressure bility of the' burner going out of Working order. Y

.In some heating systems h ot Water is boilers and consequently the oil could not be vaporized from connected to a supply the boiler itself as above described Vby using steam, but in such circumstancesthe pipe line to which the pipe 27 is connected is not attached to the dome of the boiler but is of compressed air which is designed to perform the functions of the steam. The construction of the burner however remains the same and it is therefore deemed unnecessary to redescribe the burner in combination with a compressed air reservoir.

As many changes could .bemade in the above construction and many apparently Widely different embodiments ofiny invention Within the scope of the claims, .con structed Without'departing from the'spirit or scope thereof, it is intended that all. matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limited sense. wWhat I claimas my invention is: y An oil burner of the class described comprising a tube provided with a plurality ofv curvilinear slots therein, a pipe surrounding the tube and spaced therefrom forming.

an annular passageway, a jet on the pipe having curvilinear slot-s therein, eJector means 'for delivering a mixture of oill and fluid to the tube and means for delivering fluid to the annular chamber to inter-mix,

with the fluid and oil andV complete the vaporization of the oil.

In Witness whereof l have hereunto set my hand in the presence of two Witnesses.
